The requirements for polystyrene insulation board should meet the aforementioned performance requirements, tool preparation, equipment preparation, and operating conditions, which can be referred to in the above technical regulations. The construction procedure follows the following construction points: 3.1 Basic wall treatment The wall surface should be cleaned and free of oil stains, floating dust, etc. The weathered parts should be chiseled and removed, and the protrusions on the wall surface should be leveled. After the completion of the base treatment of the insulation layer construction, polystyrene board insulation can be pasted. The polystyrene board should be pasted with staggered joints and biting. The ZL polymer mortar used for pasting the polystyrene board should be mixed according to the packaging ratio. When adjusting the mortar viscosity, it is advisable to add or subtract a suitable amount of adhesive solution, and it is strictly prohibited to add water for adjustment. When pasting polystyrene board, polymer mortar can be applied around and air ducts can be left. The middle point should be glued, and the diameter of the sticking cake should not be less than 6cm. The total bonding area should not be less than 25% of the board area.

When high-strength road repair materials are applied to road surface repair, a lot of things need to be mixed in order to achieve strength. Although high-strength road repair materials have high strength, they are relatively brittle overall. In this case, it is recommended to add steel fiber high-strength road repair materials during the mixing process, which can produce buffering under huge pressure.  

Secondly, it is necessary to choose high-strength road repair materials that solidify quickly and reach strength within 2 hours, because during road repair, it is necessary to open to traffic in a short period of time.

Then, when selecting steel fibers, it is important to pay attention to the proportion of addition, which depends on different situations, such as high-strength road repair materials and steel

Please refer to the guidance of technical personnel from the grouting material manufacturer for the proportion of fibers.

The treatment of domestic sewage is a very important part of sewage treatment. There are many types and treatment methods of domestic sewage. There are usually three types of domestic sewage classification: inorganic pollutants are mainly inorganic pollutants based on the chemical properties of the main pollutants in domestic sewage, and organic pollutants are mainly composed of organic pollutants. The electroplating wastewater from mineral processing is inorganic wastewater; Wastewater from food or petroleum processing is organic wastewater. According to the classification of industrial enterprises' products and processing objects, such as metallurgical wastewater, papermaking wastewater, coking gas, metal washing wastewater, wastewater, textile printing and dyeing wastewater, dye wastewater, leather wastewater, wastewater, and power plant wastewater.

Steel fibers need to be added during the mixing process to ensure even mixing.

Cleaning the road surface:

1. The road surface needs to be cleaned thoroughly and there should be no debris

2. Need to carve out a certain height for grouting

3. Need maintenance, watering and moisturizing the road surface

4. After the road repair, it will be open to traffic in about 2 hours.

This section applies to prefabricated insulation strip boards (hereinafter referred to as internal insulation strip boards) that are composite on the inner side of the exterior walls of residential building structures. The internal insulation board for general civil buildings can be implemented according to the reference. Exterior wall internal insulation strip board refers to prefabricated insulation strip boards with a surface density of less than 5kg/m2, a surface layer thickness of 1-15mm, a board weight of no more than 1kg, and an aspect ratio of no less than 2.5, which are composite on the inner side of the structural exterior wall. Sampling 2.1 Main inspection items. Appearance quality, allowable size deviation, surface density, and bending failure load. 2 Sampling. Take one board of the same variety and specification as a batch. If there is less than one board, take the actual production as a batch. Randomly select three boards from the batch of products as a set of test specimens to test the appearance quality, allowable size deviation, surface density, drying shrinkage value, softening coefficient, bending failure load, combustibility, main section thermal resistance, and thermal bridge area. Acceptance Rule 3.1 Determination. For the appearance quality and allowable size deviation of the internal insulation strip board, if one of them is unqualified, it is considered unqualified. If one piece of the board is found to be unqualified, it is allowed to extract two sets of specimens from the original batch and conduct a re inspection of the unqualified items. If there is still one set of unqualified items, it will be judged as unqualified. If the surface density, drying shrinkage value, softening coefficient, flexural failure load, combustibility, and main cross-sectional area of the internal insulation strip board are all qualified, it is judged as batch qualified. 2 signs. The factory products should have a quality certificate, which should include the following contents: product name and model; Manufacturer and address; Production date, production batch number, manufacturing date or number; The product inspection report should include the inspector code and the seal of the inspection department; 3 Transportation.

To build a pre mixed (dry mixed) mortar factory, regardless of its production scale, feasibility studies and overall planning and design must be conducted in the early stage of factory construction. According to the requirements of production technology, the factory building, equipment, electrical, ancillary facilities, and roads must be reasonably connected to make the entire factory form an organic whole. If the overall design planning is not well considered, it may result in high production and operation costs, unreasonable site selection and layout, and increased transportation costs. How to make the newly built pre mixed (dry mixed) mortar production project profitable in terms of input and output, and conducting feasibility studies and overall planning and design of the project are key. To conduct a feasibility study for a new ready mixed (dry mixed) mortar production project for approval, it is generally required to conduct a feasibility study for the project.
